I have a new iPhone and I'm at work with it for the first time. My iPhone found a wireless network, that appears to be work-related, though I thought my company was anti-wifi for security reasons. Since it was not password-protected, I tried to use it. Though the signal strength appears to be strong, nothing is working for me. Since I am new to using wifi networks (other than my own at home), is this normal? When you are not at home, are you just trying to get onto any random wifi signal and some work, some don't? Another related question... I noticed that the iPhone refused to do anything, like check the weather or go to cnn.com on safari, when I was trying to use this WiFi network at work. I guess the phone was fooled by the strength of the signal, but nothing was working. Why did the iPhone just quit trying altogether instead of switching over to my cell phone network, which appears to be at full strength? I had to go into the settings and turn off the wifi in order to get it to use the cell phone network. And on the cell phone network, it's back to working. Doesn't it know the wifi network wasn't doing the job?
